11mins AND. TRAnsroRrING APPARATUS.

Be it known that I, JosEPH ELsnEit, a subject ofthe Emperor of Germany,residing at V 51 Fennstrasse, Berlin, in the'EmpireofGermany, engineer,have invented certain new and useful Improvements Relating toLifting Iand Transporting pparatus, of; which the following isa specification. e

This invention relates to lifting and transporting apparatus moreparticularly applicable for use with heavy articles or loads.

Lifting and transporting appliances as hitherto constructed for hoistingheavy loads, such as locomotives, boilers, pillars, girders and thelike, forall practical purposes, only permit of the displacement oftheobject to be hoisted either upwards or down-v wards, but not of itsdisplacement or travel in a lateraldirectionto the right or left hand.

This invention has for'its object to obviate this defect and to providea device for efiecting the aforesaid lateral displacement of the work inthe frame of the liftlng appliance, or appliances, when employing morethan "one, so that it is no longer necessary to produce lateraldisplacement by the efiorts ofa number of workmen or by means of someother source of power independent of the hoist. At the sametime theaction of this device, is

independent of the height to which the load has beeniraised and the loadis rendered capable of being displacedwithin wide limits.

With a view to obtaining the results enumerated above, the platform ofthe lifting clutches, hoist carriers or thehke are provided in the knownmanner with rollers rotatable in bearings, upon which rollers the loador work is laced. In order to render the load latera y displaceable uponthis roller track with certainty and exactness at any desired height,there is arran ed upon the platform or upon the frame of t e liftingappliance, gearing adapted for efiecting a lateral movement. The pillarsof the frame of the hoisting appliance or appliances must be of suchformation that they leave a free I e Specification of Letters Patent.Patented Sept. 29, 1908. z Application fil ed;0ctober 14, 1904.SefialNo. 228,462.

' end view, front view'and a plan illustrating a modification of thelifting appliance.

fReferringto Figs. 1, 2 and 3, upon each of theparts g and g of. theframe which are rigidly'connected theone with the other at their lowerpart, are arranged two spur wheels at, a and two racks b, b, by means ofwhich the load may be raised and lowered in the known manner, a small orcomparatively light shaft (1, passing from one frame to the other,transmitting the motion from the one side to the a other, theload'resting u on the larger or stronger shaft 6. Both s afts are formed,With a square upon their extremities for the reception of cranksorratchet levers. In order that the larger shaft may not participate inthe rotation when lifting takes place, the gear wheel mounted upon itand engaging withthe toothed rack 1s arranged in such a manner as torotate freely.

Instead of two shafts arranged side by side,

a single shaft may be employed arranged within a sleeve. In this casehowever considerable friction would result and risk of bending thesleeve.

Thebearings for the shafts d and e are situated in the clutches f, theguides for which slide along the walls of the frame. In order to permitthe clutches to slide freely upon the frame, rollers 72,, h are alsoprovided.

While by rotating the crank of the shaft dithe load may be raised andlowered in the usual manner,arotation of the shaft or roller e producesalateral displacement of the load resting upon it, this load, owing tothe friction produced thereby, being caused to roll along. The shaft 6acts therefore as a mechanically operated conveyer roll, by means ofwhich the displacement of the load may be .efiected very exactly bypredetermined amounts, for example for the purpose of drillin holes ingirders.

or lifting pprposes it is of course possible to employ ot er devicesgenerally used in hoisting appliances, such for example, as screwspindles with hand wheel, worm ear and the like; driving may also beeffected by means of counter shafts or in some cases with mechanicalpower as in other hoisting flooring passed over if not too great. TheWork may also be moved to higher points, by imparting to it in the firstplace the necessary inclined osition, as it is immaterial Within the ange of friction, Whether one appliance stands higher than the other. Withthe same end in view, however, by suitably raising one end the work mayalways be kept horizontal, and by the displacement and raising of theappliances the load may be raised step by step or gradually duringtransport. The arrangement may also be such that lifting and dislacement of the load take place simultaneous y; in addition to this, itis not indispensable for the displacement that the shafts should berotated, for the shafts or rollers 6 may remain loose and the load drawnover the roller 6 by means of chain or rack gearing or the like situatedupon one of the lifting clutches or a suitable frame.

For erecting purposes it is preferable not to rigidly connect the framesg and 9, but to arrange them separately. In this case, it is of courseno longer possible to effect simultaneous driving by means of acontinuous shaft d, and raising and lowering take place separately fromeach side, either by the intermediary of gear wheels or screw spindlesor the like, as already explained, or in the known manner by means ofjacks. The shafts a may then be made of any desired length so that roommay be afforded for dealing with large sheets or plates and otherunwieldly objects. In so far as the driving mechanism is mounted uponthe shaft 0, it must in this case be made displaeeable upon the shaft,so that the frames may be arranged nearer together or further apartaccording to requirements.

Referring to Figs. 4, 5 and 6, the construc tional form illustratedtherein is intended for lifting vehicle bodies or other heavy objects ofa similar kind. Hitherto in such lifting appliances, the support hasusually been furnished by a beam m, Figs. 5 and 6, carried by the twonuts f formed of riveted plates or the like. If it is desired to employa conveyer shaft such as e, in accordance with this invention in suchlifting appliances, this may be readily effected by providing the beamwith bearings shown at n and n. for the shaft 6. For the purpose ofdisplacing or feeding the work, appropriate gear mechanism, chainmechanism or the like may in this case advantageously be employed, asshown in Figs. 4, Sand 6.

As security against incorrect displacement of the shafts locking wheelsand locking pawls may be provided.

lVhat I claim and desire to secure by Letters Patent of the UnitedStates is 1. In lifting apparatus, the combination of verticallyarranged frames, gearing cooperatively connected with the uprightportions of the said frames, a roller extending between and supported bythe frames and adapted to be raised and lowered by the gearing, andtoothed gearing for operating the said roller rotatively.

2. In lifting apparatus, the combinatiol'l of vertically arranged frameshaving racks thereon, a roller extending between the frames, gear wheelsoperatively connected with the roller, another roller also extendingbetween the said frames, gear wheels operatively connected with the saidsecond roller, carriers adapted to slide in the aforesaid frames, andmeans adapted to hold the one roller inoperative while the other isbeing worked.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses this 27th day of September 1904.
